by which the cars and the like can be driven directlyin eitherdirection, backwards or forwards, without turning round but whichhoweveris turned on the spot by turning both the front and back wheelssimultaneously whereby the risk or danger of .overturning is avoided.

The existing-motor wagons, carriages and cars do not satisfy the claimspreferred chiefly in respect of turning round, in altering the course ofthe cars which, owing. to the driving axle or wheels being unturnable,could not take sharp curves by risk or danger of overturning. Thisdanger is avoided in the resent invention by roviding for turning oththe front and bac axles.

of the carriage in the same but opposite angles in such a way that thecarriage can be turned on the spot.

The accompanying drawing shows .three forms of construction of theinvention.

Figure 1 represents, in cross section, one of the two pair of wheels.Fig. 2 shows the wheel in which the toothed wheel is fixed.

Fig. 3 shows a top-view of a steering device of the carriage, Fig. 4represents two other forms of construction of a steering arrangement,Fig. 5 gives a second form of construction of the driving mechanism, andFig. 6 shows the engaging and disengaging mechanism explaining theoperation of lever 5 and associated parts 16 to 21.

The power of the motor is transmitted to the driving gear 71. and to thedifferential mechanism 1) and the case 15, which is supported in i, bythe axle a which bears the friction wheel 'I) which is in tangent withthe friction and braking disk g which is attached to the axle of thesaid gear; and from the case 15.two axles, which are removable andflexible by the universal joints k, k and'l,-

l, protrude which drive the respective Wheels tand u, the movement forw'hichare transmitted by the said axles running in the bearings p, 1which arefastened with the springs an Q fixed on the axle 8.

On t e nave of the wheels .t and a the wheels'n, n with the inner teeth(see Fig. 9- are rigidly fixed which, being propelled by the toothedWheels m and m which arefixed in the respective axles running in tinDecc ingsp, p propel the former wheels of the carriage.

As the bogie frame 1 which is attached to I the frame 0 the carriage,canbe turned in any direction. desired by means of the worm screw 11,carried by the axle w without loosing hold, the carriage is adapted tobe turned on the spot without the danger of overturning due to the powerof guiding being an unlimited one. I

Fig. 3' shows howthe' bog e frames y, y, the springs and the Wheels 25,u and z, 2 are arranged and also the bogie frame rings 0, 0 havingscrews which are in tangent with the worm screws 11 and 11 Fig. 4 showsthe second form of construction. The steering or guiding, in this'case,is made by the right and the left screws 1*, andr and by the respectivenuts :0 and m which are connected with the movable bars 9' and j, and asthe said nuts fully catch the respective screws the threads of thelatter cannot jump off. In this arrangement the axles can be bent andthe turning motions can be quickly and easily changed by changingtheholes 31, further there are two conical wheels (1, d which facilitateturnings and driving of freight wagons, chariots and the like, which, inthe existing methods, can only be turned from one end, while in thisarrangement the wagons can be turned and driven from either end. alsoshown, by dotted lines, .the third form of construction which, if onlyone turning device is necessary for turning the carriage fromione' end,a steel ribbon or leather strap 32 or thelike is put round the. rings 0,c of the bogie frames, which are fixed at the points 1 and 2, wherebyonly one axle is enou h for turning both the axles of the whee s.

In the foregoing forms of construction having one turning wheel, agearing for turning'is arranged as shown in Fig. 3 between the turningor Worm axle w. The conical In the said Fig. 4 is wheels 18 and 19 ofsaid gearing can be coupled/with the worm axle w in such a manner thatthe couplings can be exchanged. The conical wheels areswitched orcoupled by shifting the part 16 by means of the lever 5 which isactuated from the top of the carriage and in this latter action, thebolts 21 are pushed through the openings, in the affixed disk 29, intothe openings in the conical wheels 19 whereby the said gearing with the.

said axle w are coupled.

As the holes or openings in the conical wheel 19 do not always remian inthe'right position, the bolts 21 are shiftably arranged in the casing 16the former of which are jerked into the holes, at the right moment, bysprings. The bolts of theopposite conical wheel are then drawn into thedisk 30 which turns on ballbearings 17 and 20, and the bolts can beprevented from fully coming out by any suitable means.

As the reversing of the steering device is not alone sufficient fordriving the carriage in the manner described a reversing arrangement isprovided. for as shown in Fig. 5 consisting of an axle a, which isarranged over the friction and. braking disk g, being provided with twohollow axles e, e each of which has a guiding rib f and f 1 on which thegrooves of the respective friction wheels 0, o, slide. The said frictionwheels, which can be shifted outward or inwards by the left and rightscrews or spindle 3 and the nuts 4 and 6, have at the utmost end of eachhollow axle the friction clutches 7 and 8 which are alternately coupledwith the hollow axle e by the removal of the bar 9 and its appurtenances10 and 12, and also the springs 13 and parts 22 which are movable in thepart 14. The part 12 is shiftable on the tube 23, on the latter of whichthe parts 14 and 24 are fixed, and the tube 23 is fixed on the axle a bythe screw 25 whereby when the bar 9 with it; parts is shifted to theright side, the spring 13 presses the friction part 22 towards the edgeof the socket 7 so that the latter and the hollow axle e fixed in it,are carried along with the friction wheel 0 which is shiftable on theaxle e.

When coupled as shown in Fig. 5, the right side is set free by shiftingthe bar 9 towards the right side so that the parts 10 and 12 are shiftedtowards the same direction while the socket Sand the hollow axle efollowed with the friction wheel 0 are set free.

The latter wheel now gets turned by'the fric tion disk and the part 26serves for fastening the ball bearings 27 and 28 to the axle a.
